MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Mar. 18, 1 91 3.

Application filed December 22, 1910. Serial No. 598,685.

To all whom t may concern:

Be it known that I, WILLIAM S.-HARMON, a citizen of the United States,and a resident of Arleta, in the county of Multnomah and State ofOregon, have invented certain new and useful Improvements in MechanicalMovements, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to novel improve ments in mechanical movements.

The primary 'object of my invention is to provide a simply constructedand readily operated mechanism for utilizing the dynamics of a rapidlyrotating and moving body.

Another object is to provide a means for converting the tilting motionof a swivelly held member into a vertical reciprocating motion.

A still further object is to provide a comparatively inexpensivemechanism for o-perating pump plunger-s and similar devices' actuated bymeans of rock shafts.

A. further object is to secure a flywheel to a shaft capable of rotationat great speed, said shaft rotating upon two superposed bearings of atiltably held member, the wheel traveling in a circle, the movement ofsaid'member being utilized to actuate a rock shaft. l

lll/lith these and other objects in view, the present invention consistsin the combination and arrangement of parts, as will be hereinafter morefully described and par-I ticularly pointed out in the appended claims,it being understood that changes in the specilic structure shown anddescribedI may be made within the scope of the claims without departmentfrom the spirit of the invention. l

In the drawings formin a part of Athis specification, and inwhich. ikenumerals of reference indicate similar parts in the sev-Y eralviews:-Figure 1 shows an elevational view with portions broken away of amechanisin embodying my invention. Fig. 2 shows Va top View of mymechanical movement. Fig. 3 discloses a partly lsectional detail of thesupporting gudgeon. Fig. 4 isp-.an elevational detail of the lower orend roller disclosing the arrangement of the ball bearing. Fig. 5 showsan enlargeddetai'l of the driving andy idler gears'. Fig. 6 shows amodification` of the driving shaftsupport,

and Fig. 7 a detail of the rock shaft.

In carrying out the object of my inventionI employ a base 1, having thesecuring feet 3, and the centrally disposed upstanding rack teeth 7Centrally this base has a hub 2, having a threaded opening 2', withinwhich there is adjustably held the socket gudgeon 3. Held within thesocket of the gudgeon 3 is the sphere 5 of the bolt 4, this sphere beingheld in position by means ot' the cap 10', which has an openingpermitting the end of the boltA 4 to be carried in a circular path. Heldto the cap 10 is the plate 6 having the depending circularly disposedrack teeth 8 arranged for co-action with the rack teeth y7. This plate.6 has a centrally disclosed hemispherieal socket arranged to receive thecap 10 as clearly dis posed in lFig. 3., the nut 10 threading upon thebolt 4. to hold the plate Gto the cap 10. Secured t0 this plate 6 whichis swiveled to the .gudgeon 3 are the outwardly bowed brackets 12 whichgive firm support to the annulus 13, havin@r the two parallel circularsplayed bearing edges, a and I1.

As disclosed in Fig. 1 there is an access space between the plate (i andthe annulus 13 andheld within this access space is the end ot' thedriven shaft 9, to which is adjustablly secured the fly wheel 2i. Thisfly wheel is fixed to the shaft 9 in a manner permitting the same beingcarried away from or toward the projecting end of the shaft 9.

In Fig. 1 the iy wheel 24 is .shown at the end of the shaftl 9. In Fig.6 however where the shaft is shown as Very much longer than in Fig. 1,the fly wheel 24 is shown at a point intermediate of the ends of theshaft. Secured to the end of the shaft 9, opposite the fiy wheel 2i isthe conical roller 15 arranged for (3o-action with the lower splayedbearing a.. In Fig. 1

this bearing 'a is shown as inelining toward the centeroffthe annulus,while. in Fig. 4 the lower bearing ainc'lines away from the lcenter ofthe' annulus. Held adjacent to the roller 15 is a 'cap 15', having aball race within which are held a plurality of balls 47 held in positionby means of the stay plate 49. The balls 47' are arranged to rotateagainst an outer peripheral surface of the annulus 13 and assistintaking up part of the` end thrustof the shaft 9 when in operation. Acap 15 is held in position by means of the nut 16. Secured near theopposite end of the shaft 9 and arranged ,for

co-action with the upper circular splaycd As shown in Fig. 1 the roller14 engages.

the upper bearing and the roller 15 the lower bearing, the shaft beingheld in a slightly inclined position, the highest end of the shaft beingat the end which carried the fly wheel. It is of course understood thatthe angle of the shaft 9 may be in* creased in increasing the diameterof the intermediately disposed roller 14.

The instrumentalities described form a balanced member which ispermitted a tilting movement within certain limits in being swivellyconnected to the adjustably secured gudgeon 3. The tilting movement` maybe increased or decreased by raising or lowering the gudgeon 3.

Depending from the bearing 1 are the oppositely disposed bearing ears60, within which bearings is held the rock shaft 21, the

shaft having therockarms 22, each carrying apin 23, giving pivotalsupport to a connecting link 20, two such links being used and theselinks in turn are secured to'the pins 17 projecting from the plate 6, asclearly disclosed in Fig. 1. Held immediately above the point markingthe center of the base 1, is a driving shaft 31, this shaft carrying atits lower end a driving pinion 26. This pinion 26 meshes with the pinion25 secured to the shaft 9. On rotating the shaft 31 a rotary movement isvimparted to the shaft 9, which shaft at the same time is swun in acircle about the driving pinion 26. s the vshaft 9 revolves it travelsover the twoparallel circular bearings, a and b, and in doing so tiltsthe annulus in its progressive movement. This tilting movement of theannulus and the connected plate 6 is converted into a reciprocatingmovement, and imparted to the rock shaft 21 by means of the members 20and 22. As there is a tendency of the fly wheel 24 to travel away fromthe center marked by the-gear 26, I prefer lusing an idler gear 25 shownin Fig. 4 which is held in mesh with the driving pinion 26 between thecollars 45 and 46. In this way the idler 25 takes up'part of the endthrust of the bearing 9.

.In Fig. 1 the driving shaft 31 is given support within the standard 29above, while below the shaft 31 is held within the bear ings 27supported by means of the brace arms 28,. In Fig. 6 I show amodification in which the driving shaft .31 is adjustably held in thatthe shaft 31. rotateswithinA the bearings 40 and 42, held by thebracket' 40 which is secured to a suitable support overhead. The collars45 and 44 control the position of the shaft 31 which above Iis providedwith the driving pulley 43. This pulley Igives support to a suitabledriving belt. Fig. 1 I have shown a grooved pulley 32 engaged by thedriving belt 33.

In Fig. 7 I have shown a detail of the rock shaft 21 disclosing the pumparms 23 to which thepump plungers are secured.

The shaft'9 is automatically and mechani cally balanced and held in ahorizontal or other desired plane. In order to insure the pins 17 beingheld immediately above and in alinement with the'rock shaft 21, I haveemployed the intermeshing rack teeth 7 and 8. While the annulus 13 andplate are shown as two distinct and separate parts connected by means ofthe brackets 12,it should be understood that the annulus and plate couldbe cast in one by providing a groove within which 'the projecting end ofthe shaft 9 could travel. After the shaft 9 has been started and set inmotion the same can be given a high rate of speed with but a slightexpenditure of driving power resulting in a rapid and powerful strokebeing imparted to the pump arms 23.

From the foregoing it will be seen that broadly my invention comprisesan equilibrated member having two parallel circular bearings, arevolving shaft with a ily wheel supported and 'guided by said bearings,means to swing said shaft about a'xed center located intermedi-ate ofits ends, and mechanisms connecting said equilibrated member to a rockshaft.

A device constructed according to my invention is comparativelyinexpensive and the working elements are all readily accessible andadjustable.

Having thus described my said invention what I claim as new, and desireto secure by United States Letters Patent is 1.
